Does the Brand American Eagle Run Big or Small on Clothes Sizing?

American Eagle is one of the most recognised names in global casualwear—famous for ultra-soft jeans, laid-back knits, and inclusive marketing. But despite their mass appeal, shoppers consistently ask: Does American Eagle run big or small?

If you’ve ever tried to order online and been unsure whether to size up, size down, or trust the chart, this sizing guide will help. We'll walk through how American Eagle fits across categories, compare it to UK sizing norms, and introduce you to Tellar.co.uk—your go-to free sizing tool that takes the guesswork out of shopping for 1,500+ brands, including AE.

What Is American Eagle Known For?

Founded in the U.S. in 1977, American Eagle (AE) has become a staple for comfortable, affordable clothing with a youthful, relaxed feel. Their bestsellers include:

AE Jeans (Mom, Skinny, Bootcut, and Jegging)
Graphic T-Shirts & Hoodies
Outerwear and Shackets
Loungewear & Activewear

They’re especially popular among teens and 20-somethings—but AE’s recent inclusive campaigns have broadened their reach to shoppers of all shapes and sizes.

So, Does American Eagle Run Big or Small?

Here’s the short answer:

American Eagle tends to run true to size overall—but their jeans can run slightly large in stretchy fits and smaller in rigid styles. Tops generally run a bit large for a relaxed look.

Let’s break it down in more detail by category.

American Eagle Sizing by Clothing Type

1. Jeans & Bottoms

Stretch denim styles (e.g., Jeggings, Skinny) often run large, especially after a few wears.
- Advice: Size down if you’re between sizes.
Rigid denim (no stretch) tends to be true to size, or snug on curvier figures.
- Advice: Go with your usual size or size up for comfort.
Mom jeans and baggier fits have an oversized aesthetic—but still usually stay true to size at the waist.

2. Tops (T-Shirts, Hoodies, Sweatshirts)

Most AE tops run slightly large for a relaxed, casual drape.
- Advice: Order your normal size for a slouchy fit, or size down for a neater silhouette.

3. Shackets and Outerwear

These often come oversized by design. AE's shackets and fleece jackets follow the oversized layering trend.
- Advice: True to size for layering, size down if you prefer fitted.

4. Activewear & Loungewear

AE activewear tends to be true to size, with forgiving stretch.
- Advice: Stick with your regular size unless you prefer a compression-style fit.

5. Men’s Clothing

AE men's lines tend to be true to size or generous, especially in hoodies and relaxed jeans.
- Advice: Choose your usual size unless you prefer a slim or tailored cut.

What Customers and Retailers Say

Across product reviews, forums, and retail notes (ASOS, AE.com, Urban Outfitters), feedback is consistent:

“Their jeggings stretch out quickly—definitely size down.”
“I’m a UK 10 and usually a 28 in jeans, but AE’s 28 was too loose after a few wears.”
“Super soft but runs big—size down if you don’t want it oversized.”

American Eagle themselves do provide detailed size charts, but many customers still report trial-and-error shopping—especially for jeans.

How Does American Eagle Compare to UK Sizing?

Clothing Type	AE Sizing Tendency	Compared to UK High Street	Size Recommendation
Stretch Jeans	Run large	More forgiving than Topshop/Zara	Size down if in-between
Rigid Denim	True to size	Similar to Mango or Levi’s	Stick to your usual size
T-Shirts/Hoodies	Slightly oversized	Bigger than H&M or Uniqlo	Size down for fitted look
Outerwear	Oversized by design	Larger than COS or ASOS	Size down if layering less
Loungewear	True to size	Comparable to Primark/M&S	Order your normal size

The Problem: Size Charts Aren’t Personal

Even though American Eagle offers inclusive sizing—typically 000 to 24 in women’s and XS to XXL in men’s—their sizing advice is generic. It doesn’t consider:

Your body proportions (e.g. small waist, curvy hips)
Fabric stretch
Intended fit (oversized vs fitted)
Your unit preference (cm vs inches)

This can make online shopping hit-or-miss.

Real Example: AE Jeans Fit with Tellar

Let’s say your waist is 74cm and hips 97cm. For American Eagle’s Next Level Stretch High-Waisted Jegging, the website might suggest a size 8 UK / 28 US.

But Tellar, which factors in the fabric’s stretch retention, may recommend a size 6 UK / 26 US instead—based on how quickly the fabric relaxes after wear. That’s sizing made personal.
